Aluminum foil is a common product within households. It serves various purposes; from wrapping edible items to lining baking trays for an easy wash. Industries also use this paper-thin shiny sheet for purposes such as insulation. Apart from the regular plain foils, there are also containers made from aluminum. These include products like pie plates and other kitchen containers. As much as this material serves multiple useful purposes, the question eco-conscious consumers are asking is “is aluminum foil recyclable?” In this article, we’ll answer this question to address your concerns.
Aluminum foil has key properties that make people appreciate it. One of these properties is that it serves as a barrier to oxygen, light, and bacteria. As a result, people use this material to keep food fresh, lock in moisture, and wrap certain foods for grilling. Apart from these uses, various industries incorporate aluminum into their processes and packaging. Such markets include the personal care industry, confectionery, automotive, and beverage industries.
Aluminum foil can be recycled again and again. Recycled aluminum materials are easily reformed and reused to produce other items.
Aluminum foil is a thin, paper-like sheet of aluminum. Manufacturers produce it through a rolling method from the metal. These sheets are around 0.006mm to 0.2 mm in thickness. As many homes, businesses and industries use these materials, there’s also the growing concern of the life cycle.
Many materials and products end up in one landfill or the other, thereby contributing to environmental pollution. This is why most eco-conscious consumers and businesses prioritize recycling efforts. To ensure the diversion of waste from landfills, it’s important to recycle aluminum foil. This also includes other aluminum products such as aluminum trays and cans.
Aluminum is one of the earth’s most abundant metals. It is the third most prominent element in the earth’s crust1. Globally, its production keeps steadily increasing. The output levels reached around 132.3 million tons in 20192. Most of the aluminum produced in the world comes from China. The nation produced 35.8 million metric tons just in 20193. With this massive production comes various uses in several industries and households. We have foils, aluminum cans, trays, and other containers.
We can trace the origins of the versatile aluminum foil over a hundred years ago. It became a replacement for tin foil. This material was first used in packaging in 1911. The Tobler factory in Switzerland pioneered the commercial usage of aluminum foil in food wrapping. They used it to package their chocolate bars, Toblerone. Around the 1960s, various unique ways of using the foil began to spring up.
As much as aluminum foil is recyclable, it comes with a catch - it has to be clean and free of grease. So, before tossing it into the recycling curbside bin, make sure you’ve cleaned it. If it has food waste or residues stuck to it, other recyclables can get contaminated.
Since places like homes and restaurants use aluminum foil for packaging, it is advisable to properly clean any food residue. This critical step will prevent recycling contamination, ensure they accept aluminum foil, and make it easy for recyclers to create new products.
There are two main ways of diverting aluminum foil from landfills. The first is reusing and the second is recycling. There are various innovative ways of using the foil. So, before you decide to recycle, why not try out reusing it?
Finding innovative ways to reuse aluminum foil helps to reduce waste. Before tossing the foils into the recycling bin, we’ve highlighted some reuse ideas below:
As much as aluminum foil is 100% recyclable, there’s no guarantee that all recycling centers will accept it. However, one of the best things about aluminum is the fact that we can recycle it infinitely. This saves a ton of energy that would otherwise be channeled into creating virgin products.
Sometimes, although not always, your local curbside recycling program will take your aluminum foil. However, you do need to check, as regular curbside recycling programs may not have the technology to process soiled foil and smelt the metal.
Whereas foil is made from the same material as soda cans or aluminum cans, these may be processed separately. And like most recycled materials, the answer as to what can be taken by your local recycling program can vary from city to city.
About 75% of aluminum that has been produced is still present today and used productively4. You can imagine the amount of resources that the world has preserved due to this. Recycling aluminum is a good step for various reasons. Below are some of the reasons you should start recycling:
Recycling is an environmentally-friendly option that also allows us to save energy that would otherwise be channeled into making items from scratch.
If not reused or recycled, the foil will most likely end up in landfills. This significantly contributes to pollution.
Recycling aluminum reduces the demand for constantly extracting raw material from the earth.
Aluminum is widely recycled. Unlike some materials, it can be recycled indefinitely. Recycling presents environmental benefits such as conserving resources and minimizing waste. However, before recycling, you can always consider the many innovative ways to reuse aluminum foils.
